# What is the chemical form for barium bromate?

The bromate ion is $B r {O}_{3}^{-}$. The alkaline earth barium commonly forms a $B {a}^{2 +}$ ion.
And thus the formula for barium bromate is $B a {\left(B r {O}_{3}\right)}_{2}$. All I have done is cross multiply the charges so I get a neutral salt.
